Purpose: Recent advancements in interventional radiology have made angioembolization an invaluable modality in trauma care. Angioembolization is typically performed by interventional radiologists. In this study, we aimed to investigate the safety and efficacy of emergency angioembolization performed by trauma surgeons. Methods: We identified trauma patients who underwent emergency angiography due to significant trauma-related hemorrhage between January 2020 and June 2023 at Jeju Regional Trauma Center. Until May 2022, two dedicated interventional radiologists performed emergency angiography at our center. However, since June 2022, a trauma surgeon with a background and experience in vascular surgery has performed emergency angiography for trauma-related bleeding. The indications for trauma surgeon-performed angiography included significant hemorrhage from liver injury, pelvic injury, splenic injury, or kidney injury. We assessed the angiography results according to the operator of the initial angiographic procedure. The term "failure of the first angioembolization" was defined as rebleeding from any cause, encompassing patients who underwent either re-embolization due to rebleeding or surgery due to rebleeding. Results: No significant differences were found between the interventional radiologists and the trauma surgeon in terms of re-embolization due to rebleeding, surgery due to rebleeding, or the overall failure rate of the first angioembolization. Mortality and morbidity rates were also similar between the two groups. In a multivariable logistic regression analysis evaluating failure after the first angioembolization, pelvic embolization emerged as the sole significant risk factor (adjusted odds ratio, 3.29; 95% confidence interval, 1.05-10.33; P=0.041). Trauma surgeon-performed angioembolization was not deemed a significant risk factor in the multivariable logistic regression model. Conclusions: Trauma surgeons, when equipped with the necessary endovascular skills and experience, can safely perform angioembolization. To further improve quality control, an enhanced training curriculum for trauma surgeons is warranted.

High-grade liver injury is associated with high morbidity and mortality rates. We report successful emergency angioembolization and early interventional radiology support to manage a high-grade liver injury in a 29-year-old man who presented following a fall during parachute training. Upon arrival, his blood pressure was 80/40 mmHg, and emergency ultrasonography showed a liver injury with perihepatic fluid collection. The patient's blood pressure reduced to 60/40 mmHg, and emergency angiography was performed without computed tomography (CT) (door to puncture time 36 min). After angioembolization, his blood pressure returned to 120/77 mmHg. Subsequent CT revealed no additional bleeding or hollow viscus injury. He was admitted to the Intensive Care Unit and discharged without complications 30 days after admission. In this case, emergency angioembolization (without performing CT) could successfully and safely treat a hemodynamically unstable patient with a high-grade liver injury.

The role of resuscitative endovascular balloon occlusion of the aorta (REBOA) in hemodynamically unstable pancreatic trauma is unclear. We report here a case of traumatic pancreatic bleeding controlled with REBOA and angioembolization of the splenic artery before surgery. A 65-year old man experienced blunt trauma upon falling from a height of 20 m. Computed tomography (CT) revealed distal pancreatic trauma (grade III) and contrast extravasation around the splenic artery. Shortly after CT, his systolic blood pressure was 60 mmHg and REBOA was performed for hemodynamic stability. His systolic pressure increased to 130 mmHg after balloon inflation and angioembolization of the splenic artery was performed. On angiography, no further arterial bleeding was identified and the balloon was removed. Subsequently, the patient underwent emergent laparotomy with distal pancreatectomy. There was no active bleeding during surgery and distal main pancreatic duct injury was identified. After surgery, the patient recovered without complication. In this case, hemodynamically unstable hemorrhagic pancreatic trauma was treated effectively and safely with distal pancreatectomy after REBOA with angioembolization.
Purpose: Over the past few decades, the treatment of traumatic splenic injuries has shifted to nonoperative management from surgical intervention. Although some nonoperative management failure have been reported, in most trauma centers, nonoperative management is now believed to be the treatment of choice in hemodynamically stable patients. Then, in this study, we have retrospectively evaluated our experience with traumatic splenic injury. Methods: From January 2005 to July 2009, 150 patients with blunt splenic injuries were managed in our hospital. Patients' charts were retrospectively reviewed to analyze their treatment, the patients were grouped according to those who had been admitted before October 2006, defined as the "early group", and those who had been admitted after October 2006, defined as the "late group". After the patients had been divided into two group, physiologic parameters and differences between the treatments were compared. Results: 150 patients were admitted to our hospital with blunt splenic trauma. In late group, both the surgical management rate and the nonoperative management failure rate were lower than they were in the early group. Conclusion: We expect angioembolization to effectively replace surgery for the treatment of selected patients with blunt splenic injury and to result in fewer complications.

The role of angioembolization has increased because of increases in nonoperative treatment for traumatic splenic injury. We report here a case of successful treatment of iatrogenic pseudoaneurysm of the femoral artery by thrombin injection with coil embolization. A 55-year-old female was admitted to our hospital because of blunt trauma. Computed tomography (CT) revealed a grade V splenic injury with contrast extravasation; therefore, angioembolization was performed. Three days after admission, follow-up CT scan revealed rebleeding from the spleen, and repeat angioembolization was performed. Seven days after admission, an approximately $7.0cm{\times}4.0cm-sized$ pseudoaneurysm was found on follow-up CT scan and there was no bleeding from the spleen. Although thrombin was injected into the aneurysmal sac, there was still inflow of blood, as observed on color-doppler ultrasound. Therefore, coil embolization to the neck of the aneurysm was performed. On angiography, there was no contrast filling into the sac. The size of the pseudoaneurysmal sac had decreased on follow-up CT scan, and the patient was discharged to home without complications. We successfully treated a giant pseudoaneurysm of the femoral artery using thrombin and coil embolization.

Renal injuries occur in more than 10% of patients who sustain blunt abdominal injuries. Non-operative management (NOM) is the established treatment strategy for lowgrade (I-III) renal injuries. However, despite some evidence that NOM can be successfully applied to high-grade (IV, V) renal injuries, it remains unclear whether NOM is appropriate in such cases. The authors report two cases of high-grade renal injuries that underwent NOM after embolization in a hybrid emergency room (ER) system with a 24/7 in-house interventional radiology (IR) team. A 29-year-old male visited Wonkwang University Hospital Regional Trauma Center complaining of right abdominal pain after being hit by a rope. Computed tomography (CT) was performed 16 minutes after arrival, and the CT scan indicated a grade V right renal injury. Arterial embolization was initiated within 31 minutes of presentation. A 56-year-old male was transferred to Wonkwang University Hospital Regional Trauma Center with a complaint of right flank pain. He had initially presented to a nearby hospital after falling from a 3-m height. Thanks to the key CT images sent from the previous hospital prior to the patient's arrival, angiography was performed within 8 minutes of the patient's arrival and arterial embolization was completed within 25 minutes. Both patients were treated successfully through NOM with angioembolization and preserved kidneys. Hematoma in the first patient and urinoma in the second patient resolved with percutaneous catheter drainage. The authors believe that the hybrid ER system with an in-house IR team could contribute to NOM and kidney preservation even in high-grade renal injuries.
Splenic injury is a common result of blunt trauma, and bleeding occurs mainly inside the splenic capsule and may leak into the peritoneal space. Herein, we report a case where active bleeding occurred in the splenic artery and only leaked into the extraperitoneal space. This is the first case of this phenomenon in a trauma patient in the English-language literature. Bleeding passed through the peritoneum, leaked into the anterior pararenal space, and continued along the extraperitoneal space to the prevesical space of the pelvis. Therefore, on the initial computed tomography (CT) scan, the bleeding appeared to be in the left paracolic gutter, so we suspected mesenteric bleeding. However, after the CT series was fully reconstructed, we accurately read the scans and confirmed splenic injury with active bleeding. If there had been a suspicion of bowel or mesenteric injury, surgery would have been required, but fortunately surgery could be avoided in this case. The patient was successfully treated with angioembolization.

Purpose: Hemorrhage is a main cause of death in trauma patients. The goal of this study is to describe the characteristics of trauma patients with massive bleeding and to evaluate the prognostic factors concerning their survival. Methods: This study was performed retrospectively and included trauma patients with massive bleeding who had been treated from March 2007 to August 2012. The inclusion criterion was patients who received more than 10 U of packed red blood cells within the first 24 hours after visiting the emergency department. Based on their medical records, we collected data in terms of demographic findings, mechanisms of injury, initial clinical and laboratory findings, methods for hemostasis (emergency surgery and/or angioembolization), transfusion, injury severity score (ISS), revised trauma score (RTS) and trauma and injury severity score (TRISS). We used the Mann-Whitney U test and Fisher's exact test to compare the variables between the patients that survived and those that did not. We performed a logistic regression analysis with the significant variables from the univariate test. Results: Thirty-two(32) patients were enrolled. The main mechanisms of injury were falls and motor vehicle accidents. The mean transfusion amount of packed red blood cells (PRBC) was 17.4 U. The mean elapsed time for the first hemostasis (surgery or embolization) was 3.5 hours. The initial technical success rates were 83.3%(15/18) in angioembolization and 66.7%(8/12) in surgery. The overall mortality rate was 34.4%(11/32). The causes of death were bleeding, brain swelling and multiple organ failure. The ISS(25.5 vs 46.3, p=0.000), TRISS(73.6 vs 45.1, p=0.034) and base excess(<-12 mmol/L, p=0.020) were significantly different between the patients who survived and those who did not. Conclusion: The ISS was a prognostic factor for trauma patients with massive bleeding.

Hemodynamically unstable pelvic fractures show a remarkably high mortality rate of 40% to 60%. However, their standard of care remains controversial. We report here a case of a 78-year-old woman who was admitted to the Emergency Department with pelvic pain following a fall. Based on pelvic radiography, she was diagnosed with an unstable pelvic fracture. Her blood pressure was 60/40 mmHg, and owing to her unstable vital signs, emergency angiography was performed without computed tomography (CT). Both internal iliac arteries were embolized without sub-branch selection for prompt control of pelvic bleeding. Following embolization, her vital signs were stabilized. Subsequent CT revealed free intra-abdominal air, suggesting bowel perforation had occurred and necessitating emergency laparotomy. An approximately 1 cm-sized free perforation of the small intestine was identified intraoperatively, and primary closure was performed. A retroperitoneal hematoma identified intraoperatively was not explored further because it was a non-expanding and non-pulsatile mass. The patient was admitted to the Intensive Care Unit and transferred to the general ward on postoperative day 3. In this case, the hemodynamically stable pelvic fracture with bowel perforation was successfully and safely treated by prompt angioembolization without conducting CT.
Purpose: The aim of this study was to identify clinical outcome and characteristics of trauma patients via emergency medical services (EMS). Methods: Medical records of the trauma patients visiting the emergency department were retrospectively collected and analyzed from January 2015 to June 2016 in the single institution. Of 529 registered patients, 371 patients were transported by - were enrolled. The parameters including age, gender, injury mechanism, Glasgow coma scale on arrival, presence of shock (systemic blood pressure <90 mmHg) on arrival, time to arrival from accident to emergency room (ER), need for emergency procedures such as operation or angioembolization, need for intensive care unit (ICU) admission, injury severity score (ISS), the trauma and injury severity score, revised trauma score (RTS), length of stay, and mortality rate were collected. The SAS version 9.4 (SAS Institute, Cary, NC, USA) was used for the data analysis. Results: Arrival time from the field to the ER was significantly shorter in EMS group. However, overall outcomes including mortalities, length of stay in the ICU and hospital were same between both groups. Age, ISS, RTS, and injury mechanisms were significantly different in both groups. ISS, RTS, and age showed significant influence on mortality statistically (p<0.05). Conclusions: The time to arrival of EMS was fast but had no effect on length of hospital stay, mortality rate. Further research that incorporates pre-hospital factors influence clinical outcomes should be conducted to evaluate the effectiveness of such a system in trauma care of Korea.
